Anyway, I'm doing my rave and this spittle comes out of my mouth and it winds its way very delicately through the wire fence that separates us and lands clear and bright on Denzel's lip. And we're at the beginning of the scene and I've got to do the rest of the scene, and the camera isn't on him, it's on me - and I'm fully aware that I've just spat on Denzel Washington!
